Definitions

  • the present invention relates to the public Water supply and its security against sabotage attacks through criminal elements. More recently attempts have become known several times, through attacks to public institutions, e.g. the public Passenger traffic to extort large sums from operators and one of the options available here is the threat of pollutants, Pathogens, or poisons in the public water supply network.
  • Line 1 of the public water supply is underground, mostly laid in the street area, and that too is a consumer leading house connection line 3 connected by means of a house connection slide 5, usually in such a way that the house connection slide means a clamp 7 is fixed on line 1 and a drill bit 9 combined with it the opening for Produces water extraction.
  • the house connection line 3 runs also underground to the basement of the person concerned Building wherever possible as close to the street the handover point is installed whose first fitting is a meter inlet valve. On this closes the water meter and behind it a counter outlet valve, which is already for house installation belong.
  • the peculiarity of the existing house connection is a provided in the course of the house connection line 3
  • the check valve can open any suitable way in the strand of the house connection line 3 be inserted, for example by Screw connections or by means of flange connections; both Formations considered here are welded Considered connections.
  • the check valve 12 of the first embodiment has a housing 14 made of two halves 16 and 18, which by means of a welded connecting sleeve 20 together are connected.
  • the inlet housing half 16 is in one piece formed with an inlet connector 22, which by means of a welding sleeve 24 with the house connection slide 5 is connected.
  • the outlet housing half 18 is in one piece with an outlet connection 26 formed, which by means of a welding sleeve 28 connected to the continuing house connection line 3 is.
  • both housing halves are composed from a cylindrical and a truncated cone Section, being on the inner surface of the small Truncated end of the inlet housing half 16 one Seal 30 for a valve ball 32 is arranged.
  • both halves of the housing are starting from the inner surface radial ribs 34, 36 formed between their Axial parallel end faces, the valve ball 32 out is.
  • the ribs 36 of the outlet housing half 18 have a paragraph 38 in the form of a rectangular entry their end faces to a smaller diameter.
  • a support ring 40 for a relative weak spring 42 the other end of one Pressure shoe 44 acts, which with one of the valve ball 32 facing concave surface this towards the Seal 30 applied.
  • valve ball 32 In the idle state, the valve ball 32 is from the spring 42 lightly pressed on the seal 30, as shown in FIG. 2 is shown in dashed lines. Should be tried from the External buildings supplied via the house connection line 3 Substances through overpressure in the public water supply Initiate 1, the valve ball 32 would only more firmly on their sealing seat and this prevent. If water is drawn from the building, it falls the pressure behind the valve ball and this is through the excess pressure in the water pipe 1 is lifted from the seat and the check valve opens as shown in FIG. 2. The water flows between the radial ribs 34 and 36, flows around the valve ball 32 and passes through the outlet port 26 over into the house connection line 3. ways the relatively weak spring 42 does not occur significant throttle losses.
  • the second embodiment of the check valve shown in FIG. 4 12/2 differs from the one previously considered Training only by having the ribs 36/2 of the outlet housing half 18/2 on the upstream side have a fillet 46, which in the fully open Condition of the valve as the valve ball stops 32/2 act, and that the support ring 40/2 of the spring 42/2 at the transition point of the truncated cone section of the Outlet housing 18/2 rests on outlet port 26/2. It is understood that the spring 42/2 also in the completely compressed state enough distance between leaves its coils so that the water has no essential Flow losses can occur.
  • the check valve 12/3 of the third embodiment 5 and 6 in turn consists of two housing halves 16/3 and 18/3, with a valve flap insert between them 48 is clamped, which consists of a ring 50 exists through which a pivot axis 52 runs diametrically, on which two semicircular flaps 54 are hinged are.
  • Of the Back surfaces of the semicircular flaps 54 protrude spacing posts 58, which in the fully open state of the Check valve to rest on the back surface of the each other flap come and this against each other stabilize.
  • the check valve 12/4 of the fourth form of training 7 differs from that of the first and second training essentially in that the Valve closing element not a ball, but a valve disk 60, which is connected to a shaft 62, which protrudes into a guide tube 64 that in the outlet port 26/4 of the outlet housing half 18/4 of spoke-like Holding rods 66 is held.
  • the check valve 12/5 of the fifth embodiment 8 differs from that of the fourth embodiment only in that the stem 62/5 of the valve plate 60/5 is directed to the other side, namely protrudes into the inlet connection 22/5 and accordingly in this the guide tube 64/5 held by holding rods 66/5 is arranged.
  • the tension spring 68/5 is with one End at the upstream end of the guide tube 64/5 hung and with the other end in a suitable manner on Valve disc 60/5 or in the vicinity of the stem 62/5 attached.
